Specification of Letters Patent. I Application filed June 20, 1905. 8eria11i'o.'266,168.

Patented May 8, 1906.

To aZZ whom it may concern.-

Be it known that I, LINN BOYD BENTON, a

, citizen of the United States, residin at New York city, count of Richmond, an State of New York, have invented certain new and useful Improvements in Matrix-Tiimmin and Similar Machines, fully described an represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to a machine which is. especially adapted for trimming matrixblOcks to secure the proper relation of the sides and head of the matrix-block to the matrix formed in it, which is usually called fitting the matrix, but which may be used also for trimming other articles which require to be out exactly to a line.

In trimming matrices great difficulty has con found in securin the trimming of the sides-and head of matr1x-blocks so as to osition the matrix exactly in relation to t ese, and complicated and expensive methods have been used to secure this result.

The present invention provides a machine by'which accurate trimmin so as to correctly position the matrix relative T to the sides and ead of the matrix-block may be conveniently secured.

In the accompanying drawings, forming a part of this specification, a matrix-trimming machine is shown embodying all the features of the invention in their preferred form, and this machine will now be described in detail and the features forming the invention specifically pointed out in the claims.

, In the drawings, Figure 1 is a plan view of "the machine. Fig. 2 is a side elevation of the machine. Fig. 3 is an end elevation looking to the left in Figs. 1 and 2 with parts broken away to show the construction. Fig. 4 is a section, on an enlarged scale, on the line 4 of Figs. 1 and 3. Fig. 5 is a section, on an enlarged scale, on line 5 of Fig. 3. Fig. 6 is a cross-section on the line'6 of Fig. 4. F ig. 7is an enlarged detail plan of the matrix-adjust- .ing devices and cross-section. of the microscope" with the matrix-slide part1 broken away. F 8 is a detail section of t e microscope. Fig. 9 is a cross-section on the line 9 pf 351g. 8. Figs. 10, 11, and 12 are diagrams illustratingthe positioning of the matrix.

Referringjto the drawings, A isthe baseplate of the machine, on which is mounted in suitable bearings the. motor B, which drives the shaft D, carrying the cutter-head E, havin the usual trimming-cutters e.

n front of the cutter-headE ismounted oil-standard F a microsco e G, this microscope G being carried by a side 1l,mounted to -move on block 12 on standard F and adjustable so as to position the microscope G relatively to the cuttin -line of the cutters e by amicrometer-screw having the usual 'head and by which the slide 11 is positioned along the gage 1 on the block 12.

'13 is the usual adjusting-screw for focusing the microscope, and the microscope is preferably a compound microscope of the construction shown in detail in Figs. 8 and 9, having the usual cross-lines 2. One of these lines is preferably parallel with the cuttingline and is the line located relatively to t e cutter, so that the matrix will be trimmed with the amount of the locating-line of the -microscope. The other line 2 is preferably at right angles thereto, as shown. If the cross lines' are positioned otherwise, the point of crossing of the lines may form the locator of the microscope by which the matrix is positioned for trimming.

For the purpose of positioning matrices with italicized or back sloped letters the microscope is preferably provided also.with a third cross-line or locating-line 3, which crossline is carried by a sleeve 14 in the microscope, which sleeve 14 is adjustable by a handle 15, pro'ecting outside the microscope, so that by a justing the sleeve 14 this crossline 3 may be positioned at any angle desired to the other llnes, according to the slope of the letter, as fully explained hereinafter.

Mounted to move transversely to the shaft D and below the microscope G is a carriage H, moving on a Waylon the base-plate A, the carriage being moved parallel with the cutting-line by-screw K, having handle L. 011

this carriage H is mounted the matrix-slide ositioned M; by which the matrix-block is which the matrix 1s for trimming the side edges, matrix-slide by which the matrix-block is positioned. for

trimming the head, and the clampO, by

which the matrix-block is held in position for side bearing for which the microscope hasbeen set by the screw d, this line thus forming trimming, this clamp O being preferablya loose piece. J

The matrix-slide M is adjusted to,position the matrix-block by micrometer-screw g,

having the usual head h, this slide preferably carrying ascale 4 and acting to advance the matrix bodily toward the cutters. Within the slide M is a narrow slide m, which is used for adjusting the matrix angularly under the microscope, as explained hereinafter, this slide m being actuated by the small knurled head is, running on a fixed screw 5 with a slow spiral, so that a fine ad'ustment of the matrix is secured by the hea k. The slide N which positions the matrix-blocks for trimming the head is not provided with the small slide, as this is not necessary, but is actuated to adjust the matrix-blocks relatively to the cutters e by the micrometerscrew Z, having the usual head it, the slide being shown as provided with the scale 6.

- The clamp O is forked at the end, so as to bear upon the opposite ends of the matrixblock w outside the letter, and is pressed down to lock the matrix-block 0c in position for trimming the sides by clamp-screw 17. The screw 17 is carried by a two-part block 18, adjustable in a-slot in the bar P. The slot in bar P is of such length as to permit the clamp to be used with matrix-blocks and letters of Widely different lengths. An important detail feature of this clamp is its in clined form, so that the clamp-screw 17 bearin'g upon the inclined portion will tend to force the clamp O to the right in Fig. 4, thus assuring the matrix-block being pressed firmly against the matrix-slide M during cutting and securing the proper position and trimming of the matrix-block.

The 0 eration of the machine will be understoo from a brief description. In trimming the sides of the matrix-block the ma trix-block x is first placed in position below the clamp O, as shown, and then before being lockedin position by the clamp, the matrixcarriage being moved into position with the letter under the microscope, the matrixblock a; is adjusted by the matrix-slide M until the side line of the letter (shown as the letter H) is exactly under and parallel with the cross-line 2, which extends lengthwise of the matrix-block, this line 2 thus forming the locating-line in this operation. If the side edge of the matrix-block against which the matrix-slide M presses is exactly parallel with the side line of the letter, the matrixblock may be positioned solely by the adj ustment of the matrix-slide M. There is liability, however, that the matrix-block'cannot thus be properly positioned, and for this purpose the small slide m, adjustable by the knurled head is, is used, the matrix-block being held at one corner against the matrixslide M and the other corner in the,angle of the shoulder on the end of slide 'm, and thus .cross be used as the locator,

termined by erases adjustment of the slide until tipped b the under the the side ine of the letter is exactl .microscope cross-line 2. When t 's position of the matrix-block is secured, the clampingscrew 17 is run down to clamp the matrixblock tightly by the clamp O, and thus lock the matrix-block in position for trimming. The shoulder on the end of the slide m is rovided so that the end of the matrix-b ook .may be set into the angle and pressed up against the shoulder, so as to assure the block being held in position longitudinally of the side edges. I

The use of the line 2 as the locating-line enables the arallelisrn of the side line of the letter with the cutting-line to be determined, at least for small matrices, without moving the matrix-carriage to move the side line of the letter along under the locating-line of the microscope. If the point where the lines 2 parallelism will be determined by moving the carriage, so as to move the side line. of the letter along under this locating-point. This positionlng of the matrix-block takes lace while the carriage H is in position with the matrix-block beneath the microscope, and theblock may or may not project into. the path of the cutters e, the cutter-head being stationary. If the block projects into the path of the cut-' ters, thecarriage must be moved to withdraw it. The motor being now started, the cutter-head E, with the cutters'e, is rotated and the carriage H fed by the screw K to move the matrix-block past thecutters and. trim one side edge of the matrix-block, which obviously will be trimmed exactly parallel with the side line of the letter and on the line of the cross-line 2 of the microscope. One side'edge-of the matrix-block having been thus trimmed the carriage is withdrawn, the

matrix-block reversed and positioned with the other side edge opposite the cutters, and

the operation repeated for the other side edge. The width of the matrixblock is dethe' adjustment of the slide M and'position of the scale 4: carried thereby. It will be understood that some matrices require trimming of their blocks to difierent depths on opposite sides of the matrix and that in such cases the matrix-slide M must be reset when the matrix-block is reversed.

In Figs. lOand 11 there is shown diagrammatically the tipping of thematrix-block w by the slide m, so as to swin either one end or the other outward from t e slide M, and thus properly position the matrix-block in case the inner side edge is not exactly parallel with the side edge of the letter.

If the matrix character is italicized or back-sloped, the matrix-block will be positioned for trimming in exactly the same manner, except that the cross-line 3 of the microscope will be, adjusted at the angle of the line, While the cross-line 2 is parallel with the bottom of the letter, and the I11&i 1""*l)lOCl a: will be positioned by the line 3 and the bet- I tom line'by the line 2, as illustrated in Fig. 5 12, the adjustment of the matriX-blockby the slide M or slide m being the same as previously described.

In trimming the head the matrix-block will be adjusted to the locating-line 2 of the m microscope by slide N and the cad trimmed in the same way as the side. The scale 6 is not necessary unless the matrix-foot is to be 1 trimmed to a given length, which is not usual. The slide M may be used for trimming the [5 head of short matrices or may be given such a movement as to be used for trimming the head of any matrix; but in the machine shown a separate slide N for trimming the head is used to reduce the required. movement of the slide M especially for long matrix-blocks The separate slide N is convenient also to avoid frequent resetting of the slide M by a long movement. The forked [clamp O is not used with the slide N, but a a5- single-arm clamp.
